BATTEN FOR LOOMS.

SPECIFICATION forming part of Letters Patent o. 485,886, dated November8, 1892.

Application tiled August 23, 1892. Serial No. 443.891. (No model.)

To all whom, it may concern:

.Be it known that I, OTTO W. SCHAUM, a cltizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inBattens for Looms, of which the following is a specificatlon, referencebein'g had therein to the accompanying drawings.

My invention relates to the battens which are employed in certainclasses of loomssuch2 for instance, as narrow-ware loomsand 1nparticular it relates to those battens in which the shuttles travel inarc-shaped paths that sometimes are termed circles In practice in makingbattens of this kind of the usual construction and in accordance withthe methods of working heretofore followed a great deal of time andlabor necessarily is expended in trimming and dressing the front facesof the blocks in which are formed the curved grooves in which t-heshuttles move in order that the said blocks maybe made. to properly titand guide the shuttles.

My invention has for its main objects to obviate this expenditure oftime and labor and to simplify the work ofmaking a hatten and preparingit for operation.

It also has for one of its objects to produce a batteri of improvedconstruction in which the shuttle shall be enabled to move with lessresistance and friction than usual, and in which the grooves in theupper surfaces of 'he shuttles shall be guarded from dirt and ust.

My invention will first be described in connection with the accompanyingdrawings, and then will be particularly pointed out and distinctlydefined in the claims at the close hereof. In the drawings, Figure 1 isa viewin front elevation of a batten made in accordance with myinvention, the batt-en being shown for convenience in illustrating thesame as of a length suitable for the use of two shuttles. Fig. 2 is aview of the same in rear elevation. Fig. 3 is a view of the same inhorizontal section on the line 3 3 of Fig. 1. Fig.4 isaview of one ofthe shuttles in end elevation. Fig. 5 is a sectional View of part of ahatten made without my improvement. Figs. 6 and 7 are diagrams.

At 1 is represented the hatten-beam. The shuttles are marked 2 2, andthe pinions which engage with the usual racks are marked 3 3. The saidpinions will be actuated in practice in the usual manner by any desiredform of known means for the purpose of moving the shuttles back andforth in the paths provided therefor.

At 4 4 4 is represented a series of blocks, which is applied to theupper side of the batten-beam, and at 5 5 5 a second series of blocks,which is disposed upon the blocks 4 4 4. In these blocks 4 4 4 and 5 5 5is formed, as shown, the series of intersecting curved paths 6 6, inwhich the shuttles move.

At 7 7 are the spaces which are left between the respective pairs ofblocks for the reception of the reeds and the passage of the two seriesof warp-threads. To the rear side of the hatten-beam are fastened byscrews 8 the iron plates 9 9 9, which project upwardly above the upperedge of the beam and have the respective pairs of blocks 4 4 4 and 5 55, fastened thereto in appropriate positions by the screws 10 10. Thegrooves in the blocks 4 4 4 and 5 5 5 are undercut on one side at 11 1111 11, as shown, forming an offset portion which is entered by theBauges 12 on the upper sides of the shuttles. The said iianges and theshoulder 13 are formed by cutting away the material of theshuttle-bodies to form the grooves 14,which are made therein for thepurpose of receiving the overhangiug portions 15, that are left on theblocks in front of the under-outs 11. At 16 is the rack which is formedon the under side of each shuttle for engagelnent with the pinions 3,and at 17 is a shoulder on the said under side in front of the saidrack.

So far as has yet been described, the parts of my improved hatten aresimilar in construction and operation to those of the battens commonlyin use.

In operation as the shuttles are reciprocated they are retained in theirpaths by the presence of the iianges 12 12 in the undercut. portions 1111 of the grooves in the blocks, and the shoulders 13 17 slide incontact with those port-ions of the front surfaces of the blocks whichare immediately adjacent to the sides of the grooves.

I will now explain the difference between a TOO batten embodying myinvention and one made in the old style. In the latter, as shown in Fig.5, the blocks 4: 5 have plane faces, unbroken save by the grooves forthe shuttles. In my improved batten the said blocks 4 5 have thoseportions of the faces thereof which are adjacent to the said grooves forthe shutt-lesY rabbeted or depressed, as at 2l 21, in Figs. l and 3,slightly below the general level of the surface, the bottom of therabbets being at all points equidistant from the inner p0rtions of thegrooves.

In making a hatten embodying my present invention it is necessary toobserve care in the preparation of the blocks in order that the objectsof my invention may be fully secured. Ordinarily in making and fittingthe blocks they are first secured in proper position on the hatten-beamand each of them has made therein a curved groove or grooves of acertain depth by the action of a rotary cutter-head, as showndiagrammatically in Fig. 6. The blocks are then taken oft' and each isseparately planed off on its upper surface at to insure that at allparts of the block the groove shall extend to the right depth below suchsurface to tit the shuttles. This work is necessary because it is foundto be practically impossible in securing the blocks to the iron plates 99 9 in preparing for grooving them to secure them in place in such astraight and exact manner as that they shall come exactly right. In thisoperation of planing, which is performed by hand, some of the blocks areusually planed less than others, which necessitates scraping the thickerblocks while fitting in the shuttles. n

In making a hatten embodying my invention I proceed as indicated in Fig.'7-that is to say, I form on the cutting-tool on each side an extra lipor projection 0,', which as the deep groove is being made cuts a shallowrabbet 2l on the face of the block, dressing the said face to within afixed distance of the bottom of the groove. This renders me entirelyindependent of the accuracy orinaccuracy of the position of the blocksas occupied by them when secured to the plates 9 prepara- Vtory to beinggrocved, because no matter whether or not the upper face of a block liesunder the cutting-tool in a horizontal plane the lips a of thecutting-tool will cut away all such surplus material as may require tobe removed in order to secure a predetermined distance between thebottom of the groove and the top Surface of' the rabbet. Exactly thatsame distance is secured all along the block and on every block from oneend of' the hatten to the other, and this without it being necessary totake any block off from the batten after the grooving for the purpose ofdressing the same by hand to correct unevenness. The final fitting in ofthe shuttles thereby is grealy facilitated.

The improved results which are secured by my invention willbe apparentfrom the following: In finishing battens both the blocks and theshuttles are given a high finish and polish. In the case ot' the oldform of blocks (shown in Fig. 5) the varnish and polishing compoundsform a coating on those portions of the faces of the blocks which areadjacent to the grooves and on which the shoulders of the shuttle move.The polish usually is composed largely of' shellac, which When Warmth isgenerated through the friction consequent'upon the movements of theshuttles becomes sticky and rough. This defect is obviated in myimproved hatten, for therein the shoulder left at the outer line of therabbet forms a line of demarcation up to which the polish may be laid onthe face ofthe block with perfect safety, for with care none need beapplied to the depressed face of the rabbet, such face being below thegeneral surface of thebody of'the block. I f

When dust and dirt collect upon or fall against the face of a blockformed as heretofore, they are likely in falling thence to pass into thegrooves of the shuttles. This does not occur with the rabbeted block,for the raised portions of its surface thereof overhang the rabbetedportions and deflect or shed the dirt and dust, so as that they seldompass into the grooves of the shuttles.

I claim as my inventionl. The combination, with the shuttles, of thehatten-blocks formed with the curved or arc-shaped grooved paths orcircles for the shuttles and having the faces thereof adjacent to saidpaths slightly rabbeted or depressed below the general level of thesurface, substantially as described.

2. The combination, with the shuttles, of the batten-blocks formed withthe curved or arc-shaped paths or circles for the shuttles and havingthe faces thereof adjacent to said paths slightly rabbeted or depressedbelow the general level of the surface, with the bottoms of the rabbetsat all points equidistant from the inner portions of the grooves,substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
